System for use of a microprocessor for drawing of winners in a lottery with an
in advance given dividend, at which each
lottery ticket includes at least one counter of bingo type with a number in
rows and columns provided numbers as well as for the
lottery ticket unique identification. The identification of each lottery
ticket and number row of a counter are stored in a first
register which is readable by a microprocessor, that a number of number
sequences are created and stored in a second register which is
readable by a microprocessor, in such a way that each of the number sequences
is unique and gives a number of prize-winning
rows of numbers among the counters, which number corresponds to the given
dividend. One of the number sequences in the
second register is selected by a random draw. The microprocessor compares this
chosen number sequence with the number rows in
the first register and shows the identifications that indicate counters with a
prize-winning row of numbers.
L'invention concerne un système permettant d'utiliser un microprocesseur pour le tirage de loterie avec un dividende donné à l'avance, chaque billet de loterie comprenant au moins une fiche de type loto avec des numéros en rangées ou colonnes ainsi qu'un indicatif unique du billet de loterie. L'indicatif de chaque billet de loterie et la rangée de chiffres de ladite fiche sont stockés dans un premier registre qui peut être lu par un microprocesseur, et un certain nombre de séquences de numéros sont créées et stockées dans un second registre lisible par un microprocesseur de façon que chaque séquence de numéros soit unique et donne un certain nombre de rangées de numéros gagnants parmi les fiches, ledit numéro correspondant au dividende donné. Une des séquences de numéros du second registre est sélectionnée par tirage au sort. Le microprocesseur compare cette séquence de numéros choisie aux rangées de numéros du premier registre et désigne les indicatifs qui indiquent les fiches présentant une rangée de numéros gagnants.
